Abstract: PURPOSE: To obtain a clear pattern in a direction perpendicular to a selected direction, by providing an optical system with irises to make a large light passage region in the selected direction and a small light passage region in another direction.  
     CONSTITUTION: An iris is composed of moving plates 3, 3' and a base plate 2 having an aperture 1. The moving plates 3, 3' are displaced in a direction X to adjust the aperture of the base plate 2 to increase or decrease the size of light passage regions. When such irises are applied to a Moire topographic unit, the iris for a projecting lens L 1  is made slender in the direction of the lines of a projection grating G 1  and the other iris for an imaging lens L 2  is made slender in the direction of the lines of an observation grating G 2  so that a clear pattern can be projected or imaged in a direction perpendicular to the lines of the gratings. As a result, a Moire fringe contour image of high accuracy can be formed. Thus, a clear Moire contour image can be obtained even for an examined body of large depth and the accuracy of measurement is raised.

Abstract: PURPOSE:To contrive the simplification for the configuration of the control circuit for the number of turns of a brushless DC motor by a method wherein pulse width control is applied to a semiconductor switching element for driving armature winding by a time function wave, speed signal and fundamental frequency signal or positioning signal. CONSTITUTION:A speed setting circuit 11 produces a speed setting signal ea1 by a speed reference signal ef and a speed signal es. And a comparator 13 compares a triangular wave eR from a time function generator 12 with the speed setting signal ea1 and the output ec becomes a pulse-shaped switching signal and is applied to the emitters of subtransistors T1-T3. Meanwhile, voltage signals e4-E6 converted the position detection signals from hall devices H1-H3 by comparators C1-C3 for logical comparation and transistors T10-T12 are applied to the bases of the T1-T3. Therefore, collector potential e7 becomes like (j) for example, and the T2, T3 do the same operation at each energized period. If a load becomes heavy and rotary speed decreases, the speed setting signal becomes ea2.
